State of Tennessee v Horace Williamson
Robbery in bar parking lot ends in double homicide
| Crime | In the early morning of August 17, 2018, a group of four friends was robbed by masked and armed suspects in the parking lot of a Nashville bar, The Cobra. This crime ended in the deaths of Jaime Sarrantonio and Bartley Brandon Teal. |
| Evidence | An allegedly stolen vehicle was recovered after the crime. Swabs were taken from several spots on the vehicle, including the interior front passenger side door handle. |
| DNA | The Metro Nashville Police Department Crime Lab produced DNA data from the vehicle door swabs. |
| Match | Using manual interpretation, the crime lab was able to identify a partial major contributor from the evidence data. However, the lab was unable to make any comparisons to the minor contributor due to the limited minor DNA data obtained. |
| TrueAllele | TrueAllele connected the front passenger door handle swab to Mr. Williamson with a match statistic of 277. |
| Cybergenetics | On June 23, 2023 Cybergenetics analyst Jennifer Bracamontes testified before a Davidson County jury about the TrueAllele DNA results. |
| Outcome | On June 27, 2023, a Davidson County jury returned a guilty verdict on all 13 charges against Mr. Williamson. He was sentenced to life in prison without the possibility of parole. |
